Title: The Alikayasi Canyon–Channel System (Miocene, Southeast Turkey) Compared with the South Brae Fan System (Upper Jurassic, North Sea); Characterizing Sand and Gravel-Filled Channel Complexes in Coarse-Grained Deep-water Systems Without Gravel Cone Geometries
Abstract: The Alikayasi canyon–channel system of the Miocene Maras Basin, eastern Turkey, is compared with the South Brae fan, South Viking Graben, United Kingdom sector, North Sea, demonstrating the importance of outcrop analogs to subsurface oil reservoirs. The Alikayasi canyon–channel is a coarse-grained, deep-water slope depositional system that developed in a contractional tectonic setting south of a large continental landmass. Sediment was fed through large, stable river systems and fan deltas, across a relatively narrow continental shelf, through gullies directly into the head of the slope system. Coarse sediment supply at Alikayasi was continuous, but periodic increases in tectonism caused increases in depositional slope, and hence canyon-cutting. First-order erosional surfaces mark such pulsed reactivation of the canyon–channel complex system. During slope steepening, canyon reincision took place, with sediment bypass downdip to the south. Backfilling of the canyon–channel complex system, alternating with pulses of sediment bypass, occurred during periods of more stable tectonic conditions, where the development of channel–overbank systems with aggradational channel levee elements is recognized.
